Antonio Damasio, a psychology, neuroscience and neurology professor at the University of Southern California, received the prize for his somatic marker hypothesis, a proposal that emotions influence the way people make decisions.

He developed the idea after years of gathering evidence that people with certain brain injuries had difficulty making personal and social decisions even when their intellects remained intact. His studies led him to suggest that the brain process used to evaluate choices involves emotion as well as rational thinking.

His proposal first ran counter to dominant theories in his field but has since had a major influence in contemporary psychology, neuroscience, neurology, psychiatry and philosophy.

“Damasio’s pioneering work showed that emotions, by way of decision-making, are indispensable for the construction of social behavior, and that specific brain systems are responsible,” award director Woody Petry said. “His work has had an impact in the study of drug addiction, social communication, neuroeconomics, the biology of moral decisions—even education and the law.”

Damasio directs the Brain and Creativity Institute at USC, where he is David Dornsife Professor of Neuroscience and professor of psychology, neuroscience and neurology.

Since 1996, when he unveiled the core of his somatic marker hypothesis in a Proceedings of the Royal Society article, scholars have cited his writings about the idea more than 30,000 times.

A former president of the Behavioral Neurology Society and the Academy of Aphasia, he has a doctorate and medical degree from University of Lisbon in his native Portugal and has received many honorary doctorates from universities in Europe and America.

Among his many honors are the Honda Foundation’s Honda Prize, the Prince of Asturias Prize for Scientific and Technical Research, the American Psychoanalytic Association’s Presidential Medal and the International Psychoanalytical Association’s Outstanding Scientific Achievement Award.

UofL presents four Grawemeyer Awards each year for outstanding works in music, composition, world order, psychology and education. The university and Louisville Presbyterian Theological Seminary jointly give a fifth award in religion. This year’s awards are $100,000 each.
